Cascading Style Sheets (CSS) is not case sensitive. However, font families, URLs
to images, and other direct references with the style sheet may be. The trick is

the CSS class names will be case sensitive for some browsers. It is a good idea
to avoid naming classes where the only difference is the case, for example: div.myclass
{ ...} div.myClass { ... } If the DOCTYPE or XML declaration is ever removed from
your pages, even by mistake, the last instance of the style will be used, regardless
of case.
